LU/AS 1.7

Bou nou jul brug. Volg jul geskrewe instruksies en bring veranderinge aan, indien nodig.

LU/AS 1.8

Toets en evalueer die struktuur.

OPDRAG 4:

Stel as groep ten minste vyf vrae op oor die vereistes waaraan die brug moes voldoen.

LU/AS 1.10

Voorbeelde:

a) Is die brug ±50 cm lank?

b) Kan die brug ‘n gewig van 200 g ondersteun?

c) Is die brug ±10 cm breed?

d) Bestaan die vakwerke uit ewe groot driehoeke?

e) Is die papierstrooitjies stewig aan mekaar geheg?

OPDRAG 5:

Ruil nou jul vrae uit met ‘n ander groep s’n en laat daardie groep jul brug eerlik evalueer deur al die vrae te beantwoord. Moenie slegs Ja of Nee antwoord nie, maar motiveer jul antwoorde.

LU/AS 1.10

OPDRAG 6:

As julle as groep die brug weer moes ontwerp en bou, watter aanbevelings sou jy as individu hê. Skryf ten minste vyf aanbevelings van jou eie neer.

LU/AS 1.10

OPDRAG 7:

Beskryf kortliks jou aandeel in die ontwerp en bouproses deur ‘n kruisie in die toepaslike kolom te maak en met goeie redes te motiveer. ‘n aandeel.

Assessering

Leeruitkomstes(LUs)
LU 1
TEGNOLOGIESE PROSESSE EN VAARDIGHEDEDie leerder is in staat om tegnologiese prosesse en vaardighede eties en verantwoordelik toe te pas deur gepaste inligtings- en kommunikasietegnologie te gebruik.
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder die volgende doen :
Ondersoek:
1.2 vind uit oor bestaande produkte wat relevant vir ‘n probleem, behoefte of geleentheid is, en identifiseer en vergelyk die ontwerpaspekte daarvan (bv. vir wie dit is, waarvoor dit is, hoe dit lyk; waarvan dit gemaak is, hoe dit werk, of dit die omgewing sal affekteer);
1.3 voer, waar gepas, ‘n wetenskaplike ondersoek uit oor begrippe wat relevant vir ‘n probleem, behoefte of geleentheid is deur wetenskapprosesvaardighede te gebruik;
Ontwerp:
1.4 skryf of kommunikeer ‘n ontwerpopdrag vir die ontwikkeling van ‘n produk met betrekking tot ‘n gegewe probleem, behoefte of geleentheid en stel die tegnologiese doel van die oplossing duidelik;
1.5 stel minstens twee alternatiewe oplossings vir die probleem, behoefte of geleentheid voor wat duidelik met die ontwerpopdrag en met gegewe spesifikasies en besprekings (bv. mense, doel, veiligheid, omgewingsimpak, voorkoms) skakel, en teken dit aan;
Maak:
1.7 ontwikkel planne met besonderhede oor die stappe om dinge te maak, insluitend tekeninge of sketse wat help om die planne duidelik te stel;
1.8 kies en gebruik gepaste gereedskap en materiaal om produkte te maak deur die gekose materiaal af te meet, uit te merk, te sny of te skei, te vorm of te vervorm, aan mekaar te heg, te las of saam te voeg, en af te rond;
1.9 werk doeltreffend en veilig;
Evalueer:
1.10 evalueer die produk volgens die ontwerpopdrag en gegewe spesifikasies en besprekings (bv. mense, doel, omgewingsimpak, veiligheid, voorkoms), en stel verbeteringe en wysigings voor, indien nodig;
1.11 evalueer die aksieplan wat gevolg is en stel verbeteringe en wysigings voor, indien nodig;
Kommunikeer:
1.12 maak gepaste sketse (bv. tweedimensionele sketse van idees met byskrifte, uitgebreide tekeninge van finale oplossing en tekeninge met afmetings) om verskillende inligting gepas en doeltreffend te kommunikeer.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
